Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Components

Remove the Wheel
- Use a jack to lift the vehicle.
- Secure with jack stands.
- Remove lug nuts and take off the wheel.
Inspect Brake Rotors
- Check for warping using a runout gauge.
- If warping exceeds manufacturer specifications (usually 0.002 inches), replace the rotor.
Replace Brake Pads
- Remove the caliper by unbolting it from the bracket.
- Slide the caliper off and support it without stretching the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper alignment.
Reinstall Caliper and Wheel
- Reattach the caliper over the new pads.
- Torque caliper bolts to manufacturer specifications (usually around 25-35 Nm).
- Reinstall the wheel and torque lug nuts to specification (typically around 120 Nm).

3. Check Wheel Alignment and Balance

After replacing brake components, have the wheels balanced and aligned to ensure even tire wear and proper handling.
